Working Theory

Get rid of stock rev / speed limitations and augment the performance level potential of your EFI car. Magnum REV PRO Holden Calais Rev Limiter is a unique control device that has been designed to work with all vehicle ECM’s. Adjustable RPM limiting is provided by a microcontroller that selects the RPM in increments of 20 1/min throughout the rotational speed range. Limiting is accomplished by overriding the PCM’s base signal. Magnum Revolution Pro Holden Calais Performance CDI box, is a programmable Voltage-Controlled Crystal Oscillator (VCXO) with uniquely extended frequency range that is designed to override the factory Rev Limiter and the speed governor in order to get rid of suffering factory RPM speed restrictions. As a beneficial side effect, it accelerates the injection timing that can only be exploited if the fuel curve settings is remapped as well. Apart from the higher top end needs, a fuel injection remap is a must in conjunction with Magnum Holden Calais rev limiter to max out engine horses and achieve maximum acceleration with fine throttle sensitivity. Magnum Performance CDI plugs into the factory Engine computer, specifically to the quartz oscillator that is soldered onto the Electronic Engine Management board which supplies the base signal for operation of the Engine computer. With two push buttons you can easily raise or even drop the stock Rev limit in a range of + / - 20%. This fully Adjustable Holden Calais car RPM limiter neither affects engine reliability nor durability, unless you are racing or over-extending your engine.

An adjustable Holden Calais RPM limiter provides more precise control over ignition and RPM limit than the original components built in by the manufacturer. stock CDI Box on fuel injected engines is a surveillance-software placed in Engine management to restrict its maximum rev. This is usually implemented to prevent damage to the engine. Sometimes RPM limiter is applied to prevent an engine from reaching the point at which it develops maximum HP. This may be useful in say a rental vehicle but very vexing when fitted to racing or modified vehicles. factory Rev Governor works by interrupting the firing HP that is distributed to the sparkplugs, this prevents the engine from operating above a preprogrammed rpm known as the red line limit. On stock engines the rpm level that results with the spark being arrested is assigned with a fixed rev. REV-PRO Holden Calais Rev Limiter can be adjusted quickly and easily to reach an even or a higher revolution range than the stock set in order to override factory top end limit. stock engines will be sluggish without fuel maps reprogram to work around or over the top rotational speed. On modded cars where the engine produces power right up to redline, the increased rev limit will allow for peak performance capability and additional high-end HP.

After the early debut of remapper chips in the 90’s, ignition tuning became one of the more popular solutions to unleashing dormant horsepower of a EFI engine. With the increase in demand for ignition tuning, tuner companies invested time and money in this thriving market. This easy-to-install RPM governor provides a more aggressive advance curve compared to the stock. Did you already tune up your vehicle? Our Holden Calais Rev Limiter will bring your vehicle’s power capability even one step higher.

REV PRO Performance CDI box allows revolution to rev out much higher than stock, while advancing the ignition timing for more horses throughout the engine RPM range and more torque on the bottom end. This Magnum Tuning Holden Calais Performance CDI box increases the rev limit by 20% over the stock rev limit. In addition, REV PRO Holden Calais rev limiter implements a re-mapped timing curve which yields a perceptible increase in pony and torque. (Fuel controller recommended). Suitable for bone stock as well as modified engines.

REQUIRED SKILL LEVEL Medium Level Electronic Skill Required

REQUIRED TOOLS Special Tools Required

INSTALLATION TIME 60 up to 120 Minutes

Whether you are mechanical-minded or electronically inclined, you can install this REV PRO Do-It-Yourself with certain skills is assumed. Our step-by-step instructions will guide you through how to install your rev limiter in two hours or less. Prior to purchase, dismantle your ECU and check whether you are able to remove the silicon seal (if any) from inside and decide if you or your installer can conduct the setup. You'll need to access the factory quartz crystal. On gel-cast ECU’s the silicone removal process is not complex but takes a while. Removal can be done with the help of a heat gun and some paint thinner.

Steps

Start and allow the engine warm up until operating temperature reached.

Stop the engine and turn off the ignition key.

Find the Electronic Control Unit (ECU).

Disconnect the terminals.

Remove ECU's cover.

Locate the crystal oscillator (quartz) and solder it out.

Drill a hole onto the cover with diameter 8 mm (0,315"). Drill the hole at the most appropriate position to drive out the wire from the ECU.

Solder the original quartz oscillator to the pins inside the RPM control box (no polarity).

Ground the black wire to the engine frame or battery negative outside the ECU.

Slip in the black coaxial signal cable through the hole you drilled. Use the black flexible cable gland.

Find ECU ground (ECU case or that terminal prong which shows continuity to the engine frame or battery negative) and contact the black wire to that pad.

You have to find the quartz’s signal pad on the board, then solder the signal wire to either pad of the original quartz.

Crank the engine (timing is factory). If engine starts as normally, stop it and assemble the ECU. If engine doesn’t start, solder the grey signal wire to the other pad of the stock crystal oscillator, and retry.

Identifying the crystal oscillator within the ECU is very easy. You may find some sample images how they look like. If you are unsure feel free to contact our Product Specialists .

Keep in mind that the crystals have no polarity.

Programming with one finger

Start and allow the engine to warm up until operating temperature reached.

Press button #1 (brown) to lower and #2 (blue) to increase the RPM limit. Rev up the engine and check the tachometer.

During the adjustment, the LED will be flashing proportionately with the frequency until the LED shuts down. When the LED has shut down, the minimum or maximum RPM threshold is reached.

If you want to restore factory timing and stock RPM limit, just press both push buttons simultaneously for at least 3 seconds.

Although Rev Pro Vehicle Rev Limiter works standalone, it is highly recommended that you wire up a fuel controller to the engine like EVO-Tech, Dyno-Boost or Smart-Tune prior to the installation in order to realize higher engine performance. A fuel controller will allow you to remap the fuel trim, this is a crucial adjustment in conjunction with advanced ignition implemented by REV-PRO. Without a fuel controller REV-PRO will not perform efficiently.

There is no risk of any damage to the engine or electrical parts, if the engine is used within reason. This Rev Limiter works in conjunction with your Vehicle's engine management and does not affect engine reliability or durability. Factory timing and limit can be reset at any time pressing both push buttons simultaneously for at least 3 seconds.

Rev Pro will not trigger the check engine light (CEL, MIL, FI, SES).

Carbureted engines are not applicable.

Prior to purchase, dismantle your ECU and check whether you are able to remove the silicon seal (if any) from inside and decide if you or your installer can conduct the setup. You'll need access to the factory quartz oscillator. We strongly recommend having a certified tech install this unit if the user does not have sufficient expertise.

Even though in tuning terminology the Rev Limiter is also referred to as a CDI Box, this performance module is not equivalent to a conventional aftermarket CDI (Capacitor Discharged Ignition) box wired up to the ignition coil. THIS IS NOT A REPLACEMENT FOR STOCK THE CDI BOX.

recommend this rev fooler

Delivery was as expected. Knowledge was beyond my capabilities so I went to get it installed by my backyard hifi technician I still would recommend this rev fooler to anyone who needs higher speed for their car. I am very pleased with the results.

appreciable difference in power

I purchased for ignition correction was a must because of my aftermarket supercharger. Setup seemed rocket science at the first sight but followed instructions and it is straight forward. After running about 4 tanks of gas post tuning I've found appreciable difference in power and shift points are much smoother and truck runs much better that was great.

set up is a breeze

was a bit scary of interfering in the operation of stock PCM but I discoevered you don't have to do anything to jeopardize causing the PCM go defective as long as you are backed by electronical experience of some sort and your technical minded set up is a breeze, rev limiter utterly as described, liked the functionality, disliked its obsolte design.

rev bypass module is the true answer

Local dealer wants an arm and a leg for unlocking the rev governor and this rev bypass module is the true answer. The product works as discribed but . . . I have to draw your intention to the difficulties of wiring. Read instructions attentively prior to going ahead with your order. Even though tech guys are eager to help, you still need knowledge and experience so buy without reluctance only afterward. They ship free and super fast.

absolutely astounded

I bought this limiter to my trailblazer and added smart chip to my setup: (removed) headers, performance coils and high intention spark plug wires from (removed) you can feel the power increase across the full power band width. My truck burns fuel better than my other stock chevy. It needed expertize but chip installs in fair amount of time. I was a lil skeptical but after tests I am absolutely astounded.

GREAT PRODUCT

I BOUGHT THE REV PRO FOR MY 1994 TOYOTA MR2 TO RAISE THE STOCK REV LIMITER FROM 7200 TO 8000RPM. THERE WAS AN INITIAL PROBLEM GETTING IT TO WORK AND IT NEEDED A MODIFICATION TO BREAK INTO THE TOYOTA SYSTEM.IT IS NOW WORKING PERFECTLY.THE TECHNICAL HELP WHICH I RECEIVED VIA EMAIL FROM THIS COMPANY WAS OUTSTANDING .THIS PRODUCT NOW WORKS WELL AND MAGNUM ARE AN EXCELLENT COMPANY TO DO BUSINESS WITH.I RATE THIS COMPANY AS OUTSTANDING IN ALL WAYS.

add 1300 extra rpm

although the cdi rpm limiter was shipped reasonable amount of time, set up damaged my crystal when welding to rev pro box, instructions were vague and they referred to web site high notes, took 2 weeks to get a new crystal and make the vehicel run again, setting allowed me to add 1300 extra rpm but i dont forgive the issue

am fine with setting, speed and performance

I could finally install the rev limiter on my off road freelander and am fine with setting, speed and performance my only complain is that you have to drill the computer and pigtail is not lon enough to drive the rev limiter boksz far from the computer for setting.

top quality item

Arrived safely in 3 days and no shipping was charged: generous bonus! Rev governor bypass works exactly as described. The only con would be the hookup kit that came with the unit. Power wires are too short and no fuse came with the package. I piggybacked the wire directly into the 12 gauge wire I ran from the firewall bulkhead connector to the unit. Aside from this minor minus magnum mods are top quality item. I have a whole line of these mods on my car and never had a problem with them
